# rssdir is a simply-and-dirty script to rssify any directory on the filesystem.
#
# an example of use on the current directory :
#
# python2.5 /usr/local/bin/rssdir.py --prefix http://www.foo.be/cours/ . >rss.xml
#
# Don't really need python2.5 except for ElementTree but you are free to install it.
